Not sure if it's brave or shows a moment of being crazy a bit too much, but at least the man invested a lot for his own little country which makes other enjoy it as well. However, if it becomes profitable, I bet both Croatia and Serbia will start fighting for that part and things won't be that nice anymore.
yap i am not sure either :) but technically he was right as it was not claimed by anyone. but i think that if they allow him to start building there, that will be it, he will have a country.
